According to one side, disclosure file proposes the technology that a large amount of mobile terminals (also referred to as mobile device) is attached to wireless network by the mode can initiated with network.In an example, mobile device safeguards the low-down business of duty ratio, and this mobile device is normally static.According to one side, with be attached to for a long time wireless network unlike, the technology proposed in disclosure file utilizes single attach step, sets up long term identification symbol (LTID) of mobile device, and the overlay area (or one group of sector) residing for storing mobile equipment.Then, oneself can fully be separated from wireless network by mobile device, and starts to monitor the Paging Indicator of time slot or the time instance be arranged according to LTID.
Disclosure file describes the process initiating attachment mobile device from wireless network side.Also disclose and the mechanism of paging is carried out to unregistered mobile device in the current Radio Access Network at wireless network or core network.A potential benefit is, need to transmit data between mobile device and wireless network as long as wireless network detects, the low-down mobile device of a large amount of duty ratio just can be connected to wireless network.
In an example, for the application that some use machine to machine (M2M) to communicate, it is expected to a large amount of mobile device needs to be connected to wireless network, and wherein, each mobile device generates the data service with suitable low duty ratio.The example that it should be appreciated by those skilled in the art that M2M equipment is mobile device.According on the one hand, the mobile device being used for M2M application is called M2M equipment.Examples of these application comprise: the monitoring of intelligent instrument, building and safety system, Intelligent vending machine, electron medical treatment, remote monitoring industrial machine or facility for disease control, or rely on powered battery and do not need the M2M of the mobile device of frequent charge to apply.If this M2M equipment needs to keep connecting longer a period of time in a large number, such as, be attached to wireless network once and remain attachment, then owing to needing a large amount of connections of safeguarding (namely, the mobile device of attachment), this may be high cost or even impossible in radio systems.In addition, mobile device or M2M equipment may need to carry out with extremely low duty ratio the battery life that operates to guarantee to grow very much.
According on the one hand, for these application, people wish to have when needing with the M2M equipment of institute's addressing or one group of M2M devices exchange information, and wireless network self can initiate the mechanism of the attachment of specific M2M equipment or one group of M2M equipment.When the M2M application or the M2M application operated on M2M equipment that operate in wireless network side need to communicate with another M2M equipment or one group of M2M equipment, wireless network just can initiate attachment to the M2M equipment of request, and does not need always to keep connecting.
According to one side, in order to make safeguarding that the periodicity step of contextual information and execution needs in wireless network is to safeguard that the impact of the registration in wireless network minimizes, the attach procedure that wireless network is initiated may be used for unregistered M2M equipment in the wireless network.Therefore, in an example, the attach procedure effectively using wireless network to initiate will be supported without registration paging method.
According to one side, if the M2M equipment in a large number with very low duty ratio requires service when they are static or stay (namely they are stayed in the overlay area of identical community or one group of community) in same coverage area, then it is difficult for all M2M equipment being remain always registration.Such as, possible bottleneck can comprise following in one or more:
Consume the Storage and Processing resource in wireless network: in an example, keep registration to mean and must store some contextual information in the wireless network and safeguard, according to the quantity of institute's deployment facility, this may be unacceptable.If there is M2M equipment so in a large number, very large complexity will be needed and become originally to safeguard all information in wireless network and guarantee that information is up-to-date substantially.
Consume Radio Resource: in another example, if having registered a large amount of M2M equipment in wireless network, transmit between these M2M equipment and wireless networks even without informational needs, also may consume a large amount of Radio Resources.Such as, possible problem can comprise need to report adjacent cell or report and may need in the wireless network to be configured event, periodically update position or registration area etc.
Process/the battery resource at consumer device place: in another example, the existing process of registered M2M equipment may to produce in M2M equipment infeasible resource consumption (such as, the energy content of battery consumes), this can be avoided by carrying out nothing registration paging.Can retrain registered M2M equipment with some M2M are applied may infeasible maximum cycle to perform some periodic task, such as monitor possible paging or property reporting period and measure or event.
According on the one hand, a kind of method of the M2M equipment for serving many low duty ratios performs a kind of registration process of low duty ratio, and in an example, the method performs the one or more steps in step below:
Perform common access procedure
Be registered to network (such as, being attached)
Set up data cube computation (such as, packet data protocol (PDP) context)
Inquiry may have the server (or service layer) of the data for M2M equipment
If do not need what does, then remove connection
Remove the registration of network
Return sleep state, re-execute this process more afterwards
In an example, the registration process of low duty ratio may have negative impact.Say from wireless network side, if much M2M equipment performs the registration process of low duty ratio, thus compare actual registration process with query steps and cause sizable expense, then can produce negative impact.Such as, the process needed for wireless network side registration can be more much more than the actual treatment for querying server.Such as, if M2M equipment only want to ask server " having my things? ", then server should answer "Yes" or "No" simply.Compared with the information transmitted for complete registration, the institute that to connect etc. and process, this example only produces a small amount of information.
Further, if inquiry produces the low demand to actual data transfer, then resource may be wasted in large quantities.In an example, the size of polling interval may be considerably shorter than the expected time between the event of trigger data transmission demand.Such as, can suppose that fewer than half inquiry actually may produce some exchanges data.If a large amount of M2M equipment perform the registration process of this low duty ratio, a large amount of wastes of capacity may be produced.
In equipment end, even if when not having data service, equipment also may need the process (such as, being attached) performing high cost.In this case, the battery impact for each attachment cycle will be more significantly than suitable paging.
About entity to be checked, if do not have individual server or central service layer to need to take action (such as, transmission information) for determining whether, then may be difficult to determine which position is correct query point.Such as, M2M equipment may be had when it carries out the registration of periodically low duty ratio to need the multiple potential entity carrying out inquiring about.
For potential negative effect, registration and the query script of periodicity low duty ratio do not solve the problem of serving the M2M equipment of low duty ratios many in wireless network.
According to one side, minimize to make to need in wireless network the M2M device context safeguarded and allow the paging cycle grown very much simultaneously and do not need to register M2M equipment, a solution of this demand can comprise with without the attach procedure registered wireless network that paging is associated and initiate.
According on the one hand, refer to without registration paging and paging is carried out to mobile terminal unregistered in wireless network (such as, M2M equipment).Such as, not carrying out registration in the wireless network can make wireless network not have any contextual information about mobile terminal.Contextual information can be the positional information about mobile terminal, and it may be used for the mobile terminal finding paging to need.According to another aspect, external user (such as, being connected to server application or the middleware platform of internet) can ask to carry out paging to the wireless terminal of specific region.Carry out can comprising without registration paging the predefine rule should monitoring the listening period of this paging request for mobile terminal to mobile terminal.In an example, mobile terminal is waken up at listening period with paging receiving request.
Fig. 3 shows the example of the high-rise M2M framework of the M2M equipment with multiple attachment.According to one side, as shown in Figure 3, high-rise M2M framework uses the M2M service layer in wireless network side to communicate with the core network of wireless system.Multiple M2M application (as shown in the top in Fig. 3) carries out communicating to provide the function with M2M equipment (shown in the bottom of Fig. 3) exchange message with M2M service layer (as M2M applies shown in the square of below).In an example, if M2M equipment use wireless wide area network (WWAN) is connected to M2M service layer, then M2M equipment can use can WWAN wireless access technology communicate.For the attach procedure that the wireless network in this context is initiated, the M2M application on M2M service layer or the M2M application operated on one of them M2M equipment can ask M2M service layer to set up information exchange between the M2M application of filing a request and specific M2M equipment or one group of M2M equipment.
According to one side, M2M service layer can contact the core network of bottom wireless network (such as, WWAN), is connected to the M2M equipment of institute's addressing.Such as, if M2M equipment is current be not attached to network, then foundation is attached by it.Such as, if the M2M equipment of institute's addressing is not registered to WWAN, then it can use paging mechanism to occupy asked M2M equipment.
In an example, can by from the M2M service layer in wireless network side particular message or by common domain name system (DNS) inquire about trigger wireless network initiate attach procedure.According to one side, wireless network does not have the common contextual information of M2M equipment that M2M service layer wants addressing, therefore can introduce special beep-page message.In an example, the attach procedure that wireless network is initiated can operate as follows:
The request of attachment M2M equipment is by M2M service layer or the paging agent (such as, Serving GPRS Support Node/mobile management entity (SGSN/MME)) being arrived core network end by DNS system.
Paging agent generates beep-page message, it is similar to the beep-page message that uses in WWAN but comprises is not the long-term ID (fully qualified domain name (FQDN) such as, set up during first time contact between M2M equipment and service layer or long-term ID (LTID)) distributed by wireless network self.
M2M equipment knows how determine that it (in existing paging channel or in new paging channel) should monitor the time instance of Paging Indicator according to FQDN or long-term ID by the rule of reaching an agreement.
When M2M equipment Inspection to its by wireless network paging time, M2M equipment starts normal attach procedure.
According to one side, except distribution fully qualified domain name (FQDN) or long term identification symbol (LTID) add the Huo Yizu community, community needing to carry out paging, disclosed method allows the context by wireless network needs the M2M equipment for being not registered to wireless network to retain to reduce to almost nil.Alternatively, be feasible or required situation for carrying out registering in wireless network (such as, WWAN), the attach procedure that wireless network is initiated is for register but the equipment be not attached can also use existing paging mechanism.
According on the one hand, disclosed method comprises new paging mechanism, and this new paging mechanism may be used for current not registration but the M2M equipment having set up long-term ID (LTID) carries out paging in the wireless network.In an example, disclosed method can have flexibility to allow the paging cycle grown very much, supports the battery life that M2M equipment end is lasting.
In an example, without registration paging can comprise the steps in one or more:
Perform normal registration, be established to the connection of M2M service layer, set up the mark (such as, long-term ID) of M2M equipment.
The M2M equipment just having established its long-term ID to wireless network (that is, to core network) instruction and M2M service layer is the specific type that can use new paging mechanism.Further, core network carries out record to the community or one group of community that comprise M2M equipment overlay area, and this overlay area is mapped to the long-term ID set up of M2M equipment.According to one side, this information is the little context safeguarded in wireless network.In another example, context can also be limited to keep static (that is, not upgrading), until this context is by till M2M device request (such as, when M2M equipment moves on to another position from a position) always.
Remove and connect and remove registration.
